Hupo hwekuku ndiro zita rinozivikanwa rechirwere, mukurapa inozivikanwa sehemeralopia (kusina kunaka kwekuona kushandiswa kusvika kujekesa kuderedzwa). Munhu anotambura nezvirwere izvi, anotadza zvikuru anoona mumadekwana uye usiku, asi masikati, maonero ake anoenderera mberi.
Zvingaratidzika-dziripi huku? Ichokwadi ndechokuti kukwanisa kwevanhu, uye kune rimwe rimwe ziso, kuti rienderane nemamiriro ezvinhu nekujekesa kwakasiyana kunobva kumapikicha ekuti retina: tsvimbo nemakoni. Izvo zvinokonzera masikati, uye tsvimbo, dzine marefu photosensitivity - kweusiku. Mumakungu, kunamatira mu retina kune vanenge vasipo, uye naizvozvo pakuvira kwezuva ivo chaizvo vanove mapofu. Nokuda kwechiitiko ichi, chirwere umo vanhu vane simba nekuonekwa kweusiku, uye vainzi usiku hupofu.
Zvinokonzera usiku hupofu
Chirwere ichi chinokonzerwa nekuputsa kwechiyero pakati pehuwandu hwemakoni nematanda mumeso evanhu, kuderedzwa kwehuwandu hwehutambo kana hutano hwehutano hwehutano hwavo, uyewo nekuda kwekushaya kana kukanganiswa mukutsinhanisa kwemavara anoonekwa e rhodopsin, ari mumatanda.
Iro tsika yekusiyanisa zvitatu zveusiku bofu:
- congenital;
- Essential;
- zviratidzo.
Chinhu chinonyanya kukosha usiku hunokosha hupofu. Chirwere chacho chinogona kukura kunze kwekunze kwekushaya zvokudya zvinovaka muviri, nekuda kwekushaya mavitamini, pakutanga - vitamini A. Mukuwedzera, inogona kukonzerwa nekushaya ropa, chirwere chechiropa, kupererwa kwemuviri kwemuviri, kutarisa kune zvakasiyana-siyana zvehupfu.
Chirwere chepfungwa usiku hupofu hunopesana nehutachiona hwezvirwere zveziso, zvakadai se glaucoma, retinitis pigmentosa, high degree myopia.
Congenital usiku hupofu huzhinji hunokonzerwa nedzimwe zvirwere zvinotambura, zvikurukuru, dzinotora pigment retinitis kana Asher syndrome.
Zviratidzo zvehupofu husiku
Nechipfufu chekoko, maziso anowedzera zvakanyanya mumamiriro ekudzivirira. Kubudirira kwahwo kunopera, zvinhu zvinogona kutarisa zvakasvibiswa, zvakasvibiswa, munda wechitarisiko hauna kupera, ruvara rwemavara runoputsika. Kakawanda maonero akajeka emuvara webhuruu anotambura, kana kuti hapana mavara mavara nguva dzose mumadekwana uye usiku. Izvo zvinogonawo kuonekwa pamberi pemaziso emasikati panguva yekushanduka kubva kubva pakamuri rakavhenekera kusvikira kune rima uye shure.
Nzira yekubata sei bofu usiku?
Zvinofanira kuonekwa kuti kurapwa kwehupofu husiku hunobva pane zvawakaratidza uye izvo zvakakonzera.
Chirwere chemarudzi anokosha chinowedzera nyore nyore kurapwa. Sezvo kazhinji kacho uhu hweusiku hupofu hunokonzerwa nekushaiwa kwevhitamini A, saka kubvisa chirwere chacho zvakakwana kuti unwe mavitamini.
Kana kushaya vitamini A kwakamuka nekuda kwekudya kwemishonga iyo inopikisana nayo (somuenzaniso, quinine), mushonga unofanirwa kubviswa kamwechete uye nguva yekudya mavithamini inofanira kuitwa nokukurumidza. Apo usiku hupofu hunokonzerwa nechirwere cheropa, hutachiona uye zvimwe, chirwere chikuru chinorapwa zvikuru.
Kudzivirira kwechirwere ichi chete ndiko kudya kwakakodzera. Iwe unofanirwa kudya karoti, kabichi, michero yevirumusi, jisi mutsva, chiropa chehove uye zvipfuwo.
Uine zviratidzo zvehemorrhagia, tanga utarisa chirwere cheziso chiri pasi. Izvi zvinogona kusarudzwa magirazi akakodzera uye kushandiswa kwemishonga yakasimba ye myopia. Kutora mishonga uye, kana zvichidikanwa, kuvhiyiwa kwechirwere kana glaucoma.
Iko kusanganisa kwehusiku hupofu hahupindi mishonga, uye kune kuderera kunoramba kuripo mumasikati ekuona.
